When resolving arguments on inner classifier, one can omit the arguments
for outer class 'Outer' if they are present implicitly in the scope:
- One of the supertypes of current class is Outer
- One of the outer classes or one of their supertypes is Outer
Relevant arguments are obtained from the first type found by
the algorithm above
Note that before this commit implicit arguments were only been searched
in containing classes
#KT-11123 Fixed
23 invokes in KFunctionFromReferenceImpl (and consequently, in FunctionImpl)
were needed before 1576160390: a wrapped function
reference must have had the necessary invoke to be called as an instance of a
specific function type. After 1576160390, this is
not needed anymore because KFunctionFromReferenceImpl is now an internal
implementation detail of reflection, and no invoke is ever called on it.
Most of KClassImpl operations should be cached, but creating a lazy value for
each operation would significantly increase memory footprint of a KClassImpl
instance. Therefore we decide to store all lazy values under a single lazy
value named 'data' which is stored in KClassImpl. There's a minor overhead of
indirection on any operation now, however it'll allow us to substantially
increase reflection performance by caching everything we can
Generation of callable reference's signature in codegen should use the same
mechanism for obtaining the signature as the runtime in RuntimeTypeMapper,
namely DescriptorUtils.unwrapFakeOverride(...).original
#KT-13700 Fixed
Do not treat members with already changed signature as a reason
to create a hidden copy
See tests for clarification:
- There are `charAt` method in B that has different name in Kotlin - `get`,
i.e. relevant descriptor has initialSignatureDescriptor != null
- When collecting methods from supertypes, `charAt` from A is also get
transformed to `get`
- So it has effectively the same signature as B.get (already declared)
- If by an accident B.get had been declared with Kotlin signature
we would have add A.charAt (after transformation) with special flag:
HiddenToOvercomeSignatureClash (hides it from resolution)
- But here B.charAt was artificially changed to `get`, so no signature clash
actually happened
#KT-13730 Fixed
Replace coercion from VOID with call 'pushDefaultValueOnStack'
It's necessary because coercion of VOID to java/lang/Object ends with Unit instance on stack
that makes variables spilling algorithm thinking that variable is Unit
#KT-13409 Fixed
Before this change everything works just fine for 'handleResult' methods
accepting non-Unit parameters
For other cases the same coercion-to-unit strategy is in plain lambdas:
- if last statement is not Unit type, execute it, pop from the stack, then put Unit instance
- for 'return@label' (no expression) just put Unit on the stack
